Description
Technical field
The invention belongs to technical field of nanometer material preparation, and in particular to a kind of bionical preparation side of titania nanotube
Method.This method is to assemble assembling in bacterial cellulose gel medium by titanium source, organic-inorganic hybrid material is formed, with this material
Based on prepare titania nanotube.
Background technology
Bio-mimetic syntheses are exactly that the mechanism of biomineralization is introduced into inorganic material synthesis, using the assembly of organic matter as template,
The formation of control inorganic matter is gone, prepares the inorganic material with unique microstructure feature.Biomimetic mineralization process refers to gentle
Under the conditions of (normal temperature, normal pressure or pH are neutral) utilize organic molecules as that catalytic templating induction synthesis is a series of to have elaborate knot
The inorganic material of structure.Biomineralization process generally generates shape under the exquisite control of various biomolecule and its ordered aggregation
Looks, size and structure are by the inorganic material of intact regulation and control, thus its performance is significantly better than corresponding synthetic material.It is based on
This, the biomimetic material synthesis of biological template has evolved into a very active research field in present material science.
During bio-mimetic syntheses, template plays vital effect.It is preparation structure, property that the dry change ten thousand of template, which is changed,
The premise of inorganic material that can be totally different.Its size range of various biomaterials is situated between and seen, can lead to macroscopical large scale from microcosmic
Cross large biological molecule (albumen, DNA, polypeptide, lipid, polysaccharide etc.), microorganism (virus, bacterium, fungi etc.), animal and plant cells,
Tissue etc. obtains for template.With the development of science and technology people have higher and higher requirement to material, current design and synthesis material
The trend of material is that the material for making synthesis has multicomponent, more sizes, various structures, multiple functions and good biocompatibility
And environment friendly.
Notice is gradually transferred to molecular recognition in biomineralization process, molecule certainly by the nineties in last century, scientists
Assembling and duplication constitute multicoloured nature, and start conscious land productivity with this natural principle to instruct special material
Synthesis.It is a series of that there is better optical, electricity, the metal of magnetic property, metal oxide, carbide, nitride, vulcanization
Thing etc. is synthesized.Among numerous oxide materials to serve many purposes, titanium dioxide is as a kind of widely used
Metal oxide, turn into one of wherein most dazzling material, its biomimetic mineralization process (bionical titanizing) is widely studied.Due to
Titanium dioxide has the advantages that good optics, electrical properties, chemical inertness and biocompatibility and is widely used in light
The fields such as catalyst, solar cell, lithium ion battery, photochromic device.But the performance of titanium dioxide is not only brilliant with it
Body structure, surface nature is relevant, specific surface area also special with it, hole size, and pore volume is relevant with pore size distribution isostructuralism matter,
It is certainly that scientists are synthesized compared with common preparation method with special optical, electricity with unique texture biological template
The titanium dioxide of property provides possibility.
Nano-TiO2It is at present by one of nano material of extensive concern, has that specific surface area is big, surface tension is big, fusing point
The features such as low, magnetic is by force, absorption UV resistance is strong, surface-active is big, good heat conductivity, good dispersion, mainly should extensively
Used in photocatalysis field, including waste water treatment, purification of air, sterilization antibacterial etc., and cosmetics, weaving, ceramics, medicine and too
The fields such as positive energy battery.And the titanic oxide material of bio-mimetic syntheses is the new material for having property, there is special thing
Reason, chemical property and potential wide application prospect.A series of research of biomimetic synthesis technologies is titanium dioxide bio-mimetic syntheses
Technology further industrializes, industrialization provides transition bridge.
